IMPROVEMENT IN WlCK-RAISERS.

Specification forming part of Letters Patent No. 141,673, dated August 12, 1873,' application filed June 30, 1873.

To all lwhom it may concern.-

Be it known that I, JOHN STRAszER, of St. Louis, St. Louis county, Missouri, have invented an Improvement in Lamp-Burners, of which the following is a specification:

This invention consists in the provisionof a collar having one or more spiral projecting ribs or flanges, which act directly on the wick to elevate or depress the same as the collar is turned. This invention also cons ists in forming the collar of suitable spring metal and slotting it so that the part or parts that are screw-threaded or carry the spiral rib or ribs will form spring sections, which constantly tend to keep their spiral ribs or screwthreads embedded in the wick, and so that the spiralribs will be accommodated to the size of the wick.

Figure l is a perspective view, showing my improvement applied to. a locomotive headlight burner, the wick-operating collar being raised out of place to show its construction. Fig. 2 is an axial section, showing the parts in position. Fig. 3 is an under perspective view, showing my improvement applied to the common Argand burner. Fig. 4 is a perspective view of a modification of the wickoperating collar of the head-light burner.

A is the outer, and B the inner barrel of the body of the burner, and forming with the bottom O an annular chamber for the wick and oil, and which is connected to the oilreservoir by the usual neck a. D is a drippan, arranged below the burner, having perforations d in the sides or top to allow the passage of air through the interior of the barrel B. The collar by which the vertical adjustment of the wick is made is formed of two concentric rings, E F, united at the top. This collar iits on the top of the barrel B, and may be turned freely thereon. The inner ring F is connected by arms f to the collar G, in which is fixed the vertical rod H, that passes through the burner and through an incasing-sleeve, D', secured to the bottom of the drip-pan D, and is` provided with an operating hand-wheel, I, and nut t', which screws on the rod and holds the parts together. The rod Hat its upper end carries the adjustable dellector K. The outer ring E of the collar is slotted so as to form any required number of spring sections or wings,

e, (four of which are shown in Figs. l and 3, and two in Fig. 4,) and which are formed with spiral projecting ribs or iianges e', which are forced ont to embedthemselves in the wick L by the spring of the sections e.

In Fig. l the spring sections e are united at their middle to the rim E by the connection-pieces e, and are disconnected from each other by vertical slots, so as to have an outward spring at each end, while in Fig. et the two sections c are connected to the main part E by one vertical connecting-piece, e,

so that there are only two spring-Wings, carryin g spiralilanges, in this form.

In the modification shown in Fig. 3, the adjusting-collar E is placed outside of the wick, and its flanges e are turned inward. Its upper edge is turned outward, and serves as a means for its rotation. It is formed similarly to the collar before described, except that the inner annular part F is omitted and the spiral ribs e project inward instead ot' outward. i,

My improvement may be modified by forming or securing the spring sections c with their spiral ribs e on the barrel in contact with one side of the wick, and forming the collar on the other side of the wick with ver.y

pose set forth.
